| description | Industrialization and urbanization have produced large amounts of atmospheric and soil pollutants. Among them, heavy metals are one of the main byproducts that are widely distributed in the atmosphere, water, soil and organisms, which have a great impact on climate. It is of great significance to reduce their enrichment in soil by ecological restoration methods for the sustainable development of urban atmosphere and climate. This study investigated the effects of different garden plants (<i>Festuca arundinacea</i>, <i>Ageratum conyzoides</i>, <i>Trifolium repens</i>) mixed with <i>Brassica parachinensis</i> on plant growth, physiological indexes and Cr (chromium) content in aboveground and underground parts in Cr (the main heavy metal pollution produced by industrialization) contaminated soil. The yield of <i>B. parachinensis</i> was the highest under the mixed cropping mode with <i>T. repens</i>, with the Cr content in edible parts being lower than the standard, suggesting an effective combination of <i>B. parachinensis</i> in community gardens. The mixed cropping of <i>F. arundinacea</i> with Bra decreased <i>B. parachinensis</i> yield. Under the mixed cropping of <i>A. conyzoides</i>, the edible parts of <i>B. parachinensis</i> were aggravated by Cr pollution, which was not recommended for planting. Our results suggest that converting the monoculture mode of vegetables to mixed cropping with garden plants reduced heavy metal pollution of community garden plants and improved soil productivity and environmental quality. |
